File History

System Restore is an amazing, powerful, career-saving feature—but it’s awfully self-interested. It cares only about protecting Windows.

How can you rewind your documents to their earlier, healthier, or pre-edited conditions?

File History is a time machine for documents in the same way System Restore is a time machine for your system software. It’s an incredible safety net against damage, accidental modification, or late-night bouts of ill-advised editing. It automatically backs up files in your libraries, on the desktop, in your address book, and on your OneDrive. If anything bad happens to the originals, you’re covered. You can also rewind documents to specific dates—if, for example, you decide your novel was better before you tinkered with it last week. It’s a lot like the Time Machine feature on the Mac, in other words.
